Blackhawk's 14 dBi Yagi antenna is without a doubt the most popular installed 3G antenna in Australia. This antenna is the ideal antenna for Cel-Fi GO repeaters.
With Telstra announcing the gradual shutdown of the Telstra 3G / Next-G network over the next few years it's critical that any antenna being installed today is compatible with the Telstra 4GX (700 MHz) network which will take its place.
Blackhawk tune their Yagi antenna to a 200 MHz bandwidth @ VSWR ~2:1 from 690 to 890 MHz. This allows the one high gain antenna to operate on both 850 MHz 3G and 700 MHz 4G without any major compromise in performance.
This antenna requires little further explanation. It is high performance, designed in Queensland, and built tough for Australian conditions.
With a 14 dBi gain, the antenna is designed to operate in rural and regional areas, out to about 40 kilometres from the nearest base station. 14 dBi provides a good compromise between high gain and narrow beamwidth.
Antennas need to maintain a reasonably wide beam (around 25 degrees in this case) to capture reflected and delayed radio paths that your device's rake receiver can digitally reconstruct.
Like all high gain antenna it is important to disconnect this antenna during handling and installation. This product may generate EME that exceeds ARPANSA safety limits within 300 mm of the antenna mainlobe.
